I would recommend getting the 26mm over 22mm.

Whiteline is have 20% off and free shipping right now

26mm might be a bit too much on a street car that OP doesn’t intend on tracking? That’s really, really beefy compared to stock. Might run into oversteer.

Also, I guess not exactly relevant since I have a base model (sport) coupe, but the combo of Type R front subframe brace and rear sway bar (bought it used off a Type R owner who was upgrading) really does enhance cornering. Definitely the go-to mod for suspension performance over looks.

Go hard or go home lol. To be fair 26mm isn’t for everyone, it for die-hard canyon run, auto-cross, track day guys like me, 22mm is perfect 98% of people on this board. I like to attack my corner :headbang:

I'm with you on the rear end sitting higher and looking doofy, and I think most lowering springs drop the rear a tad more than the front. One of the most modest drops out there for lowering springs are the Eibach pro kit, which drops it 0.9" in the front and 1.1" in the back. They're likely going to be my next upgrade. However, they wont decrease body roll as much as a rear sway bar since all they are doing is lowering the center of gravity and adding a tiny bit of stiffness. I want them for mostly aesthetic purposes, but eventually want to get a sway bar as well after some tires/wheels and will likely go with the Eibach Type R 25mm rear sway bar as opposed to the 22mm options offered for the Si.

Got a link to that CTR part? Does it fit the coupe?

I'm running the Eibach bar in the rear and it made a world of difference. Didn't think it would. Still running the OEM Si endlinks on the hardest settings with no issues.
Yes it does. Fits every civic. I confirmed it personally

Is the change in driving dynamics very noticeable?
It's super easy to induce oversteer once the sway bar and endlinks are installed. Lift off the gas and graze the brakes going around a highway exit and the back end loves to come out. You go really fast and simply lifting off the gas in a corner will make the ass end step out. So fun.

I'm a Whiteline retailer, and have been running the 22mm RSB at softer setting since last September. It's plenty for 90% of the people looking for more rotation, and oversteer can be induced intentionally or unintentionally if your braking, or line is off. I have both the 22mm and 26mm in my inventory, and I'm not going near the 26 anytime soon because I want to work up to the harder setting first with the 22mm which I'll be doing so this weekend.

27mm front sway bar is also going to be installed on my Si this weekend, then in a year perhaps I'll work my way up to the 26mm rear bar. Learn the car, my advice is that you don't need the 26mm rsb unless you are a serious AutoX competitor, OR you are working your way up. Better car isn't much without a better driver ;)

honestly havent dug into a corner with it, but yes, it is noticeable. I had a RSR bar on my old civic and the stock si bar was still too small.

where i live is flat , non curvy roads- living here is kinda terrible actually for sporty cars.
